14gb/s NVME SSD!!

The first PCIe 5.0 SSD outperforms PCIe 4.0 with 14 GB/s of performance!

During the China Flash Market Summit, KIOXIA has surprised everyone by showing its first prototype of SSD with PCIe 5.0 interface, a device that is very early yet but has not left anyone indifferent since it raises the performance levels in such a way that even today’s top-of-the-range PCIe 4.0 SSDs fall short of the bitumen. Here we tell you everything that is known at this time.

Surprisingly, SSDs with a PCIe 4.0 interface have been on the market for about two years now, and new models have never stopped arriving on the market with increasingly better performance. The high-end ‘barrier’ SSDs have already twice the performance of PCIe 3.0 SSDs. As a result, we may anticipate exactly double the performance while using the PCIe 5.0 interface, as KIOXIA has previously proved.

Up to 14 GB/s on the first PCIe 5.0 SSD!

The remarkable aspect of KIOXIA’s announcement is that, contrary to prior generations, the first SSD prototype with a PCIe 5.0 interface already offers twice the performance of the best existing PCIe 4.0 SSDs. Getting to double the performance of the previous generation was made to wait in earlier generations, and originally, we had SSD that did enhance performance, but reaching double took years. 

As a result, the fact that a prototype already delivers twice what we had previously is practically a historical milestone. It is not unexpected that the first PCIe 5.0 SSD has been demonstrated by a business like KIOXIA, given that it is the world’s second largest maker of Flash memory products. 

The prototype will be part of the CD7 series and will be available in both the 2.5-inch EDSFF E3S format and the more conventional M.2 format with NVMe protocol. The devices will also be aimed at the 8- and 16-channel controller data center segments, and they will almost certainly be available sooner than consumer models.

KIOXIA PCIe 5 SSD performance!

These drives will be offered in capacities ranging from 1.6TB for the most “entry-level” model to 30TB for devices geared for companies and data centers. Another intriguing feature is that KIOXIA claims its durability to be 1-3 DWPD (in a 1,600 GB SSD and 5 years warranty this is equivalent to about 3,000 TBW, But it’s odd that the manufacturer chose DWPD instead TBW to represent durability.

Because the PCI-Express 5.0 interface will be available very soon, storage device makers are likely to be working on their first prototypes. KIOXIA expects the first CD7 Series SSDs to join the market in 2022, as new Intel and AMD platforms hit the market (it would be foolish otherwise, imagine releasing a PCIe 5.0 SSD when not there are compatible motherboards).

Keep in mind that the Intel Alder Lake-S CPUs will also support PCI-Express 5.0 (x4) links for SSDs, but the industry appears to be waiting for Phison to move the tab with its new 5th generation controller (to have Note that virtually all current 7,000MB/s PCIe 4.0 SSDs use this brand’s controller). 

Marvell has also revealed its Bravera SC5 PCIe 5.0 controller, which will be available in 2022, along with Silicon Motion’s own solution. In summary, SSD makers are already working hard to get the first SSDs with the new interface on the market as soon as possible.
